Hah, the waddling feet. I screwed up the rotation point and by the time I realised, I didn't want to go through the pain of fixing up the model, so making the leg movement look vague okay was such a pain. That was the best animation I could pull off.
I think 18 is more than I ever did. I only started counting toward the very end, it was one of the last things I added into the game.
